Body

The Body is the Etherean NFT and its token-bound account — the onchain vessel that holds everything. A 40x40 pixel art avatar, unique to you, stored fully on Ethereum mainnet.

Avatar

40x40 grid — 1,600 pixels total
4 colors — chosen from one of 8 palettes (classic, pink, ocean, amber, grayscale, lavender, crimson, mint)
2 bits per pixel — 400 bytes per avatar, stored fully onchain
Deterministic rendering — same bytes always produce the same image

Token-Bound Account

Every Etherean NFT has an ERC-6551 TBA — a smart contract wallet owned by the NFT. The TBA address is deterministic, computed from the 6551 registry, implementation address, chain ID, NFT contract, and token ID.

What lives in the TBA:

Soul NFT — the identity document + generative art
ERC-8004 Agent NFT — the agent identity (registered at soul equip time)
ETH, ERC-20s, other NFTs — anything sent to the TBA address

When you transfer the Etherean, the new owner gains control of the TBA and everything inside it. The complete identity moves as one unit.

Rendering

Avatars are rendered client-side on HTML <canvas> using putImageData. The 400 bytes are decoded into RGBA pixel data and drawn at native 40x40, then scaled with image-rendering: pixelated for crisp display at any size.
